Data stream and data packet transmission method and device

1. A data stream and data packet transmission method, comprising: detecting whether data to be transmitted is a data stream whose transmission is not interrupted or stopped or a data packet according to a control character which identifies a data transmission type; when it is detected that the data stream and the data packet need to be simultaneously transmitted through one interface, preferentially transmitting the data stream; and upon completion of transmission of the data stream, then transmitting the data packet; wherein, the step of preferentially transmitting the data stream comprises: when transmitting the data stream, after finishing transmission of the data stream, transmitting the data packet; when transmitting the data packet, stopping transmitting the data packet once the data stream needs to be transmitted, and inserting the control character which indicates interruption of transmission of the data packet into the data packet whose transmission is interrupted; and then transmitting the data stream needs to be transmitted, until finishing transmission of the data stream needs to be transmitted, transmitting the data packet whose transmission is interrupted; wherein the control character comprises: a delimiter, configured to distinguish whether data is the control character or data; a command type, configured to indicate a current link state; and state data, configured to indicate information as a packet type of the data to be transmitted and whether the data packet is interrupted.

2. The method according to claim 1 , further comprising: establishing, by sending a control character for establishing an interface link connection to an opposite end, the interface link connection with the opposite end.

3. The method according to claim 1 , further comprising: packetizing the data stream or the data packet, inserting the control character for identifying a data transmission type, and sending the packetized data stream or data packet to an opposite end.

4. The method according to claim 1 , further comprising: receiving data from the opposite end; and identifying, according to the control character in the data from the opposite end, the transmission type of the received data, and parsing out the data stream or the data packet.

5. A data stream and data packet transmission device, comprising: a transmission type detecting module, configured to detect whether data to be transmitted is a data stream whose transmission is not interrupted or stopped or a data packet according to a control character which identifies a data transmission type; and a conflict transmission processing module, configured: when it is detected that the data stream and the data packet need to be simultaneously transmitted through one interface, to preferentially transmit the data stream; and upon completion of transmission of the data stream, to transmit the data packet; wherein the conflict transmission processing module is further configured to: when transmitting the data stream, after finishing transmission of the data stream, transmit the data packet; when transmitting the data packet, stop transmitting the data packet once the data stream needs to be transmitted, and insert the control character which indicates interruption of transmission of the data packet into the data packet whose transmission is interrupted; and then transmit the data stream needs to be transmitted, until finishing transmission of the data stream needs to be transmitted, transmit the data packet whose transmission is interrupted; wherein the control character comprises: a delimiter, configured to distinguish whether data is the control character or data; a command type, configured to indicate a current link state; and state data, configured to indicate information as a packet type of the data to be transmitted and whether the data packet is interrupted.

6. The device according to claim 5 , further comprising: a link establishing and restoring module, configured to establish, by sending a control character for establishing an interface link connection to an opposite end, the interface link connection with the opposite end.

7. The device according to claim 5 , further comprising: a data packetizing module, configured to packetize the data stream or the data packet, and to insert the control character for identifying a data transmission type.

8. The device according to claim 7 , further comprising: a receiving module, configured to receive data from an opposite end; and a packet parsing module, configured to identity, according to the control character in the data from the opposite end, the transmission type of the received data, and to parse out the data stream or the data packet.

9. The method according to claim 2 , further comprising: packetizing the data stream or the data packet, inserting a control character for identifying the data transmission type, and sending the packetized data stream or data packet to an opposite end.

10. The device according to claim 6 , further comprising: a data packetizing module, configured to packetize the data stream or the data packet, and to insert the control character for identifying a data transmission type.

11. The device according to claim 10 , further comprising: a receiving module, configured to receive data from an opposite end; and a packet parsing module, configured to identity, according to the control character in the data from the opposite end, the transmission type of the received data, and to parse out the data stream or the data packet.
